Windows Command:TASKKILL

I have read about a windows CMD Command called Taskkill. This command helps us to kill/end one or more processes that is running in your local machine as well as the remote machine.
Basic Syntax:
TASKKILL [/S system [/U username [/P [password]]]]
         { [/FI filter] [/PID processid | /IM imagename] } [/F] [/T]
/S can be used if we wish to end a process in a remote machine. If it is a local machine it is not necessary to code it.
/U is used to specify the username who initiated that process.
/P is used to specify the password for the specified Username. If this is omitted, It will prompt for it while execution.
/FI is used to filter the request criteria to its finest
/PID is used to kill the process by its process ID
/IM is used to kill the process by its process Imagename
/T is an option which is similar to Kill Process Tree in Task Manager

General Example:

taskkill /IM iexplore.exe -> will kill internet explorer in loacl machine
taskkill /s wrkstn01 /IM vlc.exe -> will kill VLC player on the machine "wrkstn01"
taskkill /s l01wkst01 /u "IT Dept" /im process.exe /f /t
will kill the whole process tree of given process.exe initiated under IT Dept user of 101wkst01 machine.
